Transthoracic impedance variability to assess quality of chest compression in out-of-hospital cardiac arrest.

Background: Chest compression is a lifesaving intervention in out-of-hospital cardiac arrest (OHCA), but the optimal metrics to assess its quality have yet to be identified. The objective of this study was to investigate whether a new parameter, that is, the variability of the chest compression-generated transthoracic impedance (TTI), namely Imp , which measures the consistency of the chest compression maneuver, relates to resuscitation outcome.

Methods: This multicenter observational, retrospective study included OHCAs with shockable rhythm.

One-Year Review in Cardiac Arrest: The 2022 Randomized Controlled Trials.

Cardiac arrest, one of the leading causes of death, accounts for numerous clinical studies published each year. This review summarizes the findings of all the randomized controlled clinical trials (RCT) on cardiac arrest published in the year 2022. The RCTs are presented according to the following categories: out-of- and in-hospital cardiac arrest (OHCA, IHCA) and post-cardiac arrest care.
